Hi all! Two days ago my family and I bought four baby chicks. The Barred Plymouth Rock chick seems to be lagging behind in growth greatly, having only sprouted a couple feathers while the others (Americauna, White Leghorn and RIR) have half of their wing feathers in. The other chicks are much bigger than the Rock. Also, when they sleep the rock stands up when it sleeps and rocks back and forth on one side of the brooder, while the other three lay down together. It eats and drinks fine, but it had minor pasty butt yesterday. Should we be worried? What can we do to help it? Will it eventually catch up in size? Is this common in Barred Rock chicks? Any 2 cents will help us out. The kids have grown very attach to it. Thanks so much from the Grahams!
